Question

A plane flying horizontally at an altitude of 1 mile and a constant speed of 500 mi/hr passes directly over a ground radar station. Find the rate at which the distance from the plane to the radar station is increasing when the plane is 2 miles away from the station.

Answer 1

is it one of the related rate problem

Answer 2

yeah

Answer 3

let's draw triangle

Answer 4

yeah, I already did and in fact I solved it but I am not getting the right answer.We have a=2, b=1, and c=sqrt of 5. We are given 500mi/hr, is that derivative of A with respect to time, so da/dt?

Answer 5

is the right answer 250sqrt(3)

Answer 6

can you check the answer?

Answer 7

250sqrt3 is correct

Answer 8

did you solve it?

Answer 9

yeah good job! how did you do it?
